We know that h = 65 ft and the angle of elevation to the top is α = 56°.
x - the length of the support wire;
x · cos 56° = 65
x = 65 / cos 56°
x = 65 / 0.5592
x = 116.237 ≈ 116.2 ft ( to the nearest tenth )
Answer: The support wire is 116.2 ft long.
Answer; x = sqrt(39)
Explanation:
x^2 = AD x AC
And AD = 3, AC = 13
=> x^2 = 13 x 3
=> x^2 = 39
=> x = sqrt(39)
Answer:I am pretty sure the answer is
C. "They are perpendicular to each other."
Step-by-step explanation:
Answer: 2.5
Step-by-step explanation:
We start with m < A + m < B = m < B + m < C as the given equation. We can rearrange the two terms on the right hand side to get m < A + m < B = m < C + m < B. From here, subtract m < B from both sides to end up with m < A = m < C. The angle B terms go away entirely. This rule I used was the subtraction property of equality. The next rule to use is the symmetric property to go from m < A = m < C to m < C = m < A. This rule is basically where we can flip the two sides of the equation and the equation is the same.
